IN EFFECT. NAM...GFS AND ECMWF QPF SIGNAL IS MOST COINCIDENT
ACROSS NORTHWEST OKLAHOMA. THERE ALSO IS A SIGNAL THAT
PRECIPITATION MAY REINTENSIFY WEDNESDAY NIGHT INTO THURSDAY. AS A
RESULT...A SECOND MAXIMUM OF PRECIPITATION MIGHT OCCUR ACROSS
SOUTHEAST PARTS OF THE CWA. THERE WILL LIKELY BE A SHARP CUTOFF IN
RAINFALL AMOUNTS WITHIN OUR CWA. ABUNDANT CLOUD COVER AND
PRECIPITATION WILL KEEP TEMPERATURES AROUND 20 TO 25 DEGREES BELOW
AVERAGE ON WEDNESDAY ACROSS CENTRAL AND NORTHERN OKLAHOMA. LOW 90S
WILL BE POSSIBLE ACROSS WESTERN NORTH TEXAS WHERE PRECIPITATION
CHANCES ARE THE LOWEST. THE CHANCE OF RAIN WILL DECREASE FROM
NORTHWEST TO SOUTHEAST EARLY THURSDAY MORNING AS THE SHORT WAVE
MOVES THROUGH.

AFTER THURSDAY...THE REGION WILL CONTINUE TO BE WITHIN NORTHERLY
MID-LEVEL FLOW FOR THE FORESEEABLE FUTURE. LIGHT NORTHEASTERLY
SURFACE WINDS AND 850 MB TEMPERATURES FROM 17 TO 19 DEGREES C
WILL KEEP TEMPERATURES IN THE MID-80S ON FRIDAY. THERE IS NO
EVIDENCE OF A DEVELOPING LOW-LEVEL THERMAL RIDGE THROUGH EARLY
